Give him an "A" for ingenuity.

Four years into a 20-year sentence for illegal weapons possession, Juan Ramirez Tijerina had had enough of life in the pokey. After a conjugal visit in July 2011 with his partner, Maria del Carmen Arjona Rivero, he was packed and ready to go – literally.

Ramirez was apprehended after officers, noticing that Arjona seemed nervous as she headed for the prison exit in Chetumal, Mexico, with a bulging suitcase, unzipped the bag and found the convict inside.

He's back behind bars, and Arjona was detained.

"This is rare," says a prison spokesman. "Most of the inmates here dig tunnels, try to jump fences or take advantage of a riot to escape."
